Definitions
- the disclosure relates to an LED light source, and more particularly to an LED light source using a light-guiding module applicable with various types of LED modules.
- An LED light source is a type of solid-state lighting that utilizes light-emitting diodes (LEDs) as a source of illumination.
- LEDs convert electricity to light via current through a junction region comprising two different semiconductors, by which electrons and holes coupled at the junction region generate the light.
- LED advantages of resistance to impact and nearly limitless lifetime under specific conditions make an LED light source a cost-effective yet high quality replacement for incandescent and fluorescent lamps.
- LED modules in an LED light source use a plurality of individual LEDs to generate light reflected by a light-guiding module to obtain sufficient illumination of suitably wide distribution.
- a conventional light-guiding module is integrally fabricated and suited only for use in the type of LED light source for which its use is intended, such that in order to equip a variety of LED light sources, development and manufacture of a wide range of light-guiding module types are required, representing considerable cost and material burdens.
- FIG. 1 is an isometric, exploded view of an LED light source in accordance with a preferred embodiment of the disclosure.
- FIG. 2 is an enlarged, inverted view of a light guiding unit of the LED light source of FIG. 1 .

- each recess 23 has a dovetailed configuration as viewed from a lateral end of the frame 20 .
- Two receiving voids 26 are extended vertically through the frame 20 , located below centers of the bottom portions of the recesses 23 and communicated with the recesses 23 , respectively.
- the receiving voids 26 are spaced from each other and symmetrical relative to the longitudinal central axis of the frame 20 .
- the lower portion of the frame 20 forms three ribs 28 in each receiving voids 26 to divide each receiving voids 26 into four segments (not labeled).
- the ribs 28 are located in alignment with the extending holes 280 along a transverse direction of the frame 20 to strengthen the frame 20 .
- Each recess 23 includes two undercuts 230 defined at two opposite sides of thereof.
- the undercuts 230 of each recess 23 are parallel to each other and face to each other.
- the undercuts 230 of each recess 23 make the recess 23 have a trapezoidal cross section.
- One lateral end of each of the recesses of the frame 20 is opened to define an entrance 220 at the corresponding lateral end of each recess 23 .
- each recess 23 of the frame 20 is closed by a corresponding lateral end of the frame 20 to terminate each recess 23 .
- the cutouts 230 of each of the recesses 23 function as runners for fittingly receiving the flanges 3310 of the base 331 of a corresponding light guiding unit 33 therein, thereby mounting the corresponding light guiding unit 33 on the frame 20 .
